Assembly and Usage Manual:
3D Printed Face Shield

1. Wear gloves and make sure you are in a clean place.

Find the following three pieces of material (see photo)

  • 3D printed headband (aka brace)

  • Plastic screen

  • Piece of elastic

2. Take the elastic band and tie it to the holes at the back of the brace

3. Adjust the elastic to the required size for your head. It is important to get the tension of the elastic right.

If it is too loose, it will slide around; if it is too tight, you are likely to experience headaches

The following photos show the assembly process with a piece of yellow card, instead of the actual clear visor, for greater contrast.

4. The front of the  3D printed headband can be teased open. The outermost part is pushed upwards as shown on the attached photo (note: this is fragile)

5. Insert the visor in landscape orientation, and pull the visor around to the end of the groove

7. Pull the visor upwards through the middle

8. The visor in the final position

The plastic at the front of the headband (blue) should be in line with the plastic headband at the back (blue). The visor (yellow) should go through the headband at least 3cm. This will ensure a tight fit and the visor will not slip out.

9. Optional: If for any reason, the visor slips when correctly assembled, it can be turned upside down and a tiny amount of super glue applied on the inside of the visor where the brace (blue) and clear sheet (yellow) pieces meet.

10. Optional: You may wish to round the corners of the clear plastic sheet to stop it catching. This can be done with scissors.

The face shield is now fully assembled and ready to be used.

Cleaning and Care

Given the current shortage of PPE, you may need to clean re-use your visor. Before packaging, the headband and elastic parts have been treated with Isopropanol to minimise risk of contamination, or were stored for a minimum of 5 days to safely reduce any viable SARS-CoV-2 particles.

Cleaning recommendations, tested in partnership with other major 3D-printing companies and various labs, can be found on the following website.  These methods may be used by 3D printers prior to delivery and by people who need to re-use the masks.

Please do not use heat on these face shields.
